Flagship Qualcomm QCC3095 Bluetooth 6.2 Architecture
The FiiO BTR25 is powered by Qualcomm's advanced QCC3095 Bluetooth 6.2 platform, delivering ultra-stable wireless transmission, reduced latency, and comprehensive high-resolution codec support. Capable of receiving aptX Lossless, aptX Adaptive, LDAC, LE Audio, AAC, and SBC, the BTR25 brings bit-perfect wireless audio streaming to audiophile in-ear monitors and demanding full-size headphones.
ESS Sabre ES9069Q DAC with Dual ES9603Q Amplifiers
Engineered for acoustic purity, the audio decoding architecture pairs an ESS Technology ES9069Q high-performance 32-bit DAC with dual dedicated ES9603Q headphone amplifier chips. This fully balanced differential signal path minimizes cross-channel interference, reduces harmonic distortion to vanishingly low levels, and delivers dynamic range and black backgrounds that rival desktop-class DAC/amp stacks.
True Dual Outputs: 4.4mm Balanced and 3.5mm Single-Ended
Equipped with both a 4.4mm Pentaconn balanced output and a standard 3.5mm stereo output, the BTR25 provides effortless connectivity across modern audiophile cable terminations. The 4.4mm balanced output delivers an impressive 570mW + 570mW into 16 Ohms and over 400mW + 400mW into 32 Ohms, providing abundant clean headroom to drive planar magnetic and high-impedance dynamic headphones with authoritative bass grip.
Three Dedicated Operating Modes: PC, Bluetooth, and Phone
A tactile three-position hardware toggle switch allows instant switching between dedicated operating profiles. PC Mode functions as a high-resolution desktop USB-C DAC/amp powered via bus power. BT Mode enables wireless Bluetooth receiver functionality with USB power pass-through. Phone Mode engages direct OTG digital decoding while disabling USB charging from the connected smartphone, preventing unwanted phone battery drain on the go.
1.3-Inch OLED Real-Time Display & Detachable Magnetic Back Clip
A vibrant 1.3-inch OLED front display provides instant visual status of current Bluetooth codec, sampling rate, volume level, EQ profile, and battery status. Housed in a lightweight CNC aluminum enclosure, the BTR25 includes an innovative detachable magnetic back clip that secures firmly to clothing, belts, or bag straps, combined with a smooth multi-function rotary digital volume knob for precise gain control.
